ZD7.1.2: Saved Search Query not as expected

If I try saving a simple search query on date as e.g. yesterday and only select the inbox I get a search result with mail dublets. The resultlist have all mails that can be expanded. One single mail is in 3 places; the local inbox, in the G-mail All Mail and Important mails. In the search I didn't select either GMail All Mail or Important mail, but they are returned in the search result anyway.

This is the entry I save as a search query and it gives mail dublets:
in:inbox (date:yesterday)



But I have a second saved search query. This entry doesnt give any dublets and shows only mails in the inbox:
in:inbox (date:-0day)

Of cource I want to have no dublets in my saved searches, so how do I avoid this?

Found out myself. The search-result should be viewed message-wise and not conversation-wise.
